They say that diamonds are forever.
Consider this; the "rock" on the ring here is older than the
Earth itself. It was formed in the core of an asteroid as
the solar system was just starting. It took a collision
with another large body millions of miles distant to set it on a
collision course with Earth. The rock
is actually solid iron with trace elements of nickel, chromium,
and others that make it similar to the super alloys of today. It
is genuine Gibeon Meteorite that is over 4 billion years old
and fell from outer space and landed in Namibia, Africa sometime
in prehistory. It has a unique crystalline structure due
to it cooling over millions of years in space. Metals
native to Earth don't have this unique structure. It is
laser welded to the ring. The ring shown is 3mm
wide. Every meteorite is unique and has a certificate of
authenticity.
